8) Valve Details
Two piece construction;
Thick body and bonnet which is even double weight than standard.
|2. Bolted bonnet connection
We use ASTM A193 B8M/A194 8M for this ball valve, which is whole threaded specially used for valves and so on.
|3. Floating design
This is floating ball valve, which has a simple construction and good sealing. The ball can produce a certain displacement and press light on the the sealing surface of the outlet end to ensure that the outlet end is sealed.
Our ball is solid type, not hollow or made by plate.
|4. Pneumatic actuator operator
This ball valve adopts single act pneumatic actuator to operate the ball valve. So user can control the ball valves remotely and automatically, saving worker cost for high-end usage. More, we also offer both single act and double act pneumatic actuators which exported to Russia, Europe a lot. And the FRL is best of china as filter, regulator and lubricator. International brand as SMC, DPC, FESTO and so on are available if required.
|5. Fireproof Structure Design
ln case of fire during the use of valve, the seat ring made of RPTFE will be decomposed or damaged under high temperature and cause higher leakage. The fireproof seal ring is set between ball and seat so that after the valve seat is burnt, the medium will push the ball rapidly towards the downstream metal seal ring to form the auxiliary metal to metal sealing structure, which can effectively control valve leakage. In addition, the middle flange sealing gasket is made of metal wound gasket, which can ensure sealing even under high temperature.The fireproof structure design of floating ball valve conforms to requirements in API 607, API 6FA, BS6755 and other standards.
|6. Anti-static Structure
This ball valve is provided with the anti-static structure and adopts the static electricity discharge device to directly form a static channel between the ball and body or form a static channel between the ball and body through the stem, so as to discharge the static electricity produced due to friction during the opening and closing of ball and seat through the pipeline，avoiding fire or explosion that may be caused by static spark and ensuring system safety.
|7. Special Seat Design
Our trunnion pipeline ball valve adopts the trunnion ball structure and floating valve seat, so as to achieve lower torque under operating pressure. It uses self-lubricating PTFE and metal sliding bearing to reduce the friction coefficient to the lowest in conjunction with the high intensity and high fineness stem.
|8. Blow-out Proof Stem
Our stem adopts the blow-out proof structure.The stem is designed with the footstep at its bottom so that with the positioning of upper end cover and screw, the stem will not be blown out by the medium even in case of abnormal pressure rise in the valve cavity.
9) Applicable Notes:
1) All materials (metallic & non-metallic) shall be suitable for the full pressure rating over the design.
2) Coating is in accordance with API standard blast and primer for shipment & storage protection.
3) Asbestos is not acceptable for any valve parts.
4) As one of float ball valve suppliers, our ball valve is marked in accordance with MSS SP-25 including requirements of ASME B16.34, in addition a
stainless steel tag showing the valves tag number is attached to the valve with multi strand stainless steel wire.
5) All of our pressure containing parts (including ball, stem & seat holders) is supplied with material certification to
EN 10204-3.1 (including certified copies of original mill certificates), all other parts including bolting and seal
materials to EN10204-2.2.
6) Our customer is free to undertake inspection and witness testing, this is in addition to any witness
points required by the customer.
7) Our valves in excess of 50Kg to include lifting lugs (flanges and/or top covers shall not be used) and valves in
excess of 100Kg shall be supplied with support feet / brackets.
8) After completion of testing, our stainless steel ball valve china shall be properly dried to prevent any test liquid remaining in the valve,
preserved and fitted with protective end caps suitable for storage in a covered and enclosed desert environment.
9) Our valves shall be carefully braced and packed in wooden boxes suitable for sea freight in accordance with GB and
Zhejiang Chuanglian Valve Co., Ltd., is a manufacturer of valves.
We have all kinds of valves, as general valves of gate valve, globe valve, check valve; and on-off valves of ball valve, butterfly valve, strainer, etc.
More, our company has certificates as ISO9001, CE, PED, API.
